The oceans are an important foundation of our lives - they regulate our climate and are an invaluable source of food. However, we threaten their health by heating up the planet, over-fishing and polluting these waters.

Most people know Ted Danson as the affable bartender Sam Malone in the long-running television series Cheers. But fewer realize that over the course of the past two and a half decades, Danson has tirelessly devoted himself to the cause of heading off a looming global catastrophe—the massive destruction of our planet's oceanic biosystems and the complete collapse of the world's major commercial fisheries. In Oceana, Danson details his journey from joining a modest local protest in the mid-1980s to oppose offshore oil drilling near his Southern California neighborhood to his current status as one of the world's most influential oceanic environmental activists, testifying before congressional committees in Washington, D.C.; addressing the World Trade Organization in Zurich, Switzerland; and helping found Oceana, the largest organization in the world focused solely on ocean conservation. In his incisive, conversational voice, Danson describes what has happened to our oceans in just the past half-century, ranging from the ravages of overfishing and habitat destruction to the devastating effects of ocean acidification and the wasteful horrors of fish farms. Danson also shares the stage of Oceana with some of the world's most respected authorities in the fields of marine science, commercial fishing, and environmental law, as well as with other influential activists. Combining vivid, personal prose with an array of stunning graphics, charts, and photographs, Ocean powerfully illustrates the impending crises and offers solutions that may allow us to avert them, showing you the specific courses of action you can take to become active, responsible stewards of our planet's most precious resource—its oceans.

This open access book summarizes peer-reviewed articles and the abstracts of oral and poster presentations given during the YOUMARES 9 conference which took place in Oldenburg, Germany, in September 2018. The aims of this book are to summarize state-of-the-art knowledge in marine sciences and to inspire scientists of all career stages in the development of further research. These conferences are organized by and for young marine researchers. Qualified early-career researchers, who moderated topical sessions during the conference, contributed literature reviews on specific topics within their research field. .

What is happening in our oceans? By describing their main elements, this book shows how and why the oceans are being transformed, and suggests possible future scenarios to address this complex, yet often-asked, question. The ocean is being dramatically transformed, but the magnitude of this transformation remains unclear since the ocean is largely inaccessible and still unknown: there is more information about the outer universe than about the deepest parts of our oceans. The author, a marine biologist with extensive research experience, offers a holistic view of our oceans. Focusing on fishing, pollution and the effects of climate change, he identifies and describes the changes occurring in all marine ecosystems, and discusses the long-passed state of equilibrium.

Our oceans are hugely important, as a source of food and mineral wealth, as an environment for a vast variety of wildlife, for the role they play in climate regulation, and as part of the biogeochemical cycles of carbon, nitrogen, and other elements critical to life. Dorrik Stow explores what we know about how oceans originate and are maintained.

There's so much we don't know about what lies deep beneath the ocean's surface - and the time to find out is growing increasingly precious . . . Professor Alex Rogers is one of the world's leading experts in marine biology and oceanology, and has spent his life studying the deep ocean - and in particular the impact of human activity on the ecosystems of the oceans. In this timely, galvanising and fascinating book - replete with stunning photography of strange and beautiful creatures - Professor Rogers offers a fundamentally optimistic view of humanity's relationship with the oceans - and also a very personal account of his own interaction with the seas.

"National Geographic Explorer-in-Residence Enric Sala takes readers on an unforgettable journey to 10 places where the ocean is virtually untouched by man, offering a fascinating glimpse into our past and an inspiring vision for the future. From the shark-rich waters surrounding Coco Island, Costa Rica, to the iceberg-studded sea off Franz Josef Land, Russia, this incredible photographic collection showcases the thriving marine ecosystems that Sala is working to protect. Offering a rare glimpse into the world's underwater Edens, more than 200 images take you to the frontier of the Pristine Seas expeditions, where Sala's teams explore the breathtaking wildlife and habitats from the depths to the surface--thriving ecosystems with healthy corals and a kaleidoscopic variety of colorful fish and stunning creatures that have been protected from human interference. With this dazzling array of photographs that capture the beauty of the water and the incredible wildlife within it, this book shows us the brilliance of the sea in its natural state."--
